Watermelon and Strawberry smoothie

This is the time of year where watermelon and strawberries are ripe, delicious and pretty much always on sale at the store.  We bought a huge watermelon earlier and some 'buy one get one free' strawberries, chopped them up and threw them in the freezer. I filled the blender with mostly watermelon, a few strawberries, some juice and about a half cup of vanilla yogurt.
The girls love them!
